The seed corn to be shelled is placed in the hopper 22 and then; passes into thelinte'rior of the'device'and in between the elements 2'and 3c and the rotating member member 12 is rotated and 'theears of corn pass- 10 I2. This rotating 7 ing between the elements 2 and 3 and the rn'emf ber I2; are moved circumferentially because of 1 the projections l8 and 19 on the member i2, and";

the grainsof corn, instead of being knocked rbietween the non-metallic flexible projections extendingtherealong, said projections elastically V loose fromrthe cob and thereby damaged, as has been heretofore thecase, are rubbed loose from the cobby the friction of the projections}, 18, l8 and 19, without damaging the grains.
